Core Advantages

· Excellent Thermal Insulation and Energy Saving: The closed-cell foam structure is filled with numerous independent, static air bubbles, forming an effective thermal insulation layer with low thermal conductivity. This significantly reduces cooling loss, helping to reduce energy consumption and electricity consumption in refrigeration equipment.

· Comprehensive Tight Seal: The highly elastic foam perfectly fills the gap between the door and door frame, achieving a 100% effective seal, effectively preventing cold air leakage, hot air intrusion, and the passage of dust, insects, and moisture.

· Superior Weather Resistance and Longevity: The core EPDM material provides excellent resistance to ozone, UV rays, and aging. Even under frequent door opening and closing, it maintains its elasticity and softness, resists permanent deformation or cracking, and has a service life far exceeding that of ordinary PVC.

· Stable Performance over a Wide Temperature Range: It remains stable and resistant to hardening and cracking in extreme temperatures as low as -50°C, and remains soft and resistant to failure in short-term high temperatures of +120°C. Its stable and reliable performance fully meets the demands of harsh environments such as cold storage and quick-freeze storage.

· Safe and Environmentally Friendly: It is non-toxic and odorless, meeting the hygiene and safety standards of the cold chain in the food and pharmaceutical industries. It offers excellent corrosion resistance and is resistant to common cleaning agents.


Main Applications

· Various Cold Storages: Sliding and hinged door seals for quick-freeze storage, freezer storage, cold storage, and controlled atmosphere storage.

· Refrigerated Transport Equipment: Door seals for refrigerated trucks and refrigerated containers.

· Temperature Control Equipment: Door seals for walk-in test chambers, constant temperature and humidity chambers, and insulated boxes. Commercial Refrigeration: Door seals for supermarket refrigerated display cases and beverage freezers.
